Does 1-propanol expected to have a higher boiling point than ethyl methyl ether

Indeed it is. Reasons being that the hydrogen bonds in the 1-propanol is difficult to break. Hence, more energy or heat is needed to be applied. Ethyl methyl ether on the other hand doesn't have hydrogen bonds and that explains why it has a lower boiling point.
*try drawing their structural formula, from there you'll be able to differentiate better*

Ithink carbon dioxide, i am not completely sure.tell me if i am wrong.

Increase temperature
